Description
[0001] The invention relates to a brake lining carrier plate to
hold a friction lining, especially for installation into a vehicle
brake system. The brake lining carrier plate has holding structures
for the friction lining arranged in rows on the lining side,
whereby each holding structure has a depression and a protrusion,
the protrusion being made when the depression is formed in the
surface through the displacement of material. Said protrusions
engage with the friction lining.
TECHNICAL BACKGROUND
[0002] Brake lining carrier plates entail the risk that so-called
edge lifting of the friction lining occurs on the brake lining
carrier plate, which can cause the friction lining to shear off
from the brake lining carrier plate when subjected to high braking
torques. Edge lifting refers to the separation of the friction
lining at its outer contour or in the area of its edges from the
brake lining carrier plate. Such edge lifting may be caused by the
penetration of moisture, water, salt water, and the like, into this
outer contour or edge area. Edge lifting also possibly may be
caused by rusting of the brake lining carrier plate brought about
by said moisture penetration.
[0003] With the known brake lining carrier plates, edge lifting is
facilitated primarily by the depressions in the holding structures
that are present in the edge area on the brake lining carrier plate
as a result of the production process. Moisture, water, salt water,
and the like, can accumulate in these depressions, thus penetrating
between the friction lining held on the plate and the brake lining
carrier plate.
[0004] WO 00/49308 A1 discloses a brake lining carrier plate of the
type being discussed herein in which holding structures are
arranged in rows. Each holding structure has a protrusion that is
arranged in the direction of the longitudinal axis of the brake
lining carrier plate. As a result, it is not possible to adapt the
holding structures on the brake lining carrier plate to the outer
contour of the friction lining in such a manner as to avoid the
edge lifting effect. Since a depression in the form of a groove or
channel has to be worked in the brake lining carrier in order to
produce the protrusions, for the rows running in the lengthwise
direction, there is a depression at least at the beginning or end
of each row. Moisture can accumulate in said depression between the
lining carrier plate and the brake lining, thus causing an edge
lifting effect. Moreover, through the alignment of the rows of the
holding structures in the lengthwise direction, the crosswise edges
of the brake lining, which are especially stressed during braking,
are affected, so that the risk of the brake lining shearing off
from the brake lining carrier plate is especially great.
[0005] U.S. Pat. No. 4,799,579 A1 describes brake lining carrier
plates with holding structures having protuberances and depressions
which are arranged in rows in the direction of the longitudinal
axis of the brake lining carrier plate. As a result, there is also
a risk of an edge lifting effect there since moisture can
accumulate in the depressions arranged in the edge area of the
brake lining.
[0006] It would be desirable to provide a brake lining carrier
plate that avoids the risk of a detachment of the friction lining
from the brake lining carrier plate, especially in the edge area of
the brake lining.
SUMMARY OF THE INVENTION
[0007] According to one aspect of the invention, a brake lining
carrier plate is provided wherein the holding structures in the
rows are arranged in such a way that there is a protrusion at the
beginning and at the end of each row. In this manner, the holding
structures can be adapted to the outer contour of the friction
lining without the rows beginning or ending with depressions. This
counteracts an accumulation of moisture in front of the first
protrusion at the beginning of the rows or behind the last
protrusion at the end of the rows.
[0008] According to a first embodiment of the invention, the
holding structures have at least two sections with an opposing
arrangement of the protrusion and of the depression of the holding
structures. As long as the opposing sections are arranged at the
opposite ends of the rows, the manufacturing process can then
easily fulfill the requirement that there should be a protrusion
(or a crimp) at the beginning and at the end of each row. Moreover,
as a result, the holding bond effectuated between the brake lining
carrier plate and the friction lining by the holding structures can
withstand greater stress. In this manner, the friction lining can
absorb greater braking forces without the friction lining shearing
off from the brake lining carrier plate.
[0009] If the free ends of the protrusions (or crimps) face forward
or else, for example, face backward (like a burr), the friction
lining can then also absorb greater forces that are exerted in a
direction perpendicular to the surface of the friction lining, for
example, when the brake is lifted.
[0010] In another embodiment of the invention, the rows of holding
structures run essentially in the direction of the longitudinal
axis of the brake lining carrier plate. Consequently, the rows are
arranged in the same direction or in the opposite direction of the
shear forces that are exerted on the brake lining carrier plate or
friction lining during braking. Thanks to this measure, precisely
at the especially highly stressed edges of the friction lining,
which run crosswise, there is no depression at the beginning or at
the end of a row, but rather always a protrusion. As a result, edge
lifting effect is avoided. Hence, the friction lining is prevented
from shearing off from the brake lining carrier plate in an
especially effective manner.
[0011] As an alternative, the rows also can run essentially
crosswise to the longitudinal axis of the brake lining carrier
plate. The manufacturing process for such an arrangement is simple
and allows an adaptation of the holding structures to each specific
friction lining contour, even in the critical edge areas of the
friction lining, without the rows beginning or ending with
depressions. In particular, this achieves an arrangement of the
holding structures on the brake lining carrier plate that ensures
optimal holding conditions for the friction lining.
[0012] According to a further refinement, the position of the
protrusion and of the depression of the holding structures
alternates between adjacent rows. Insofar as the free ends of the
protrusions point in one direction, that is to say, in the
manufacturing direction of the holding structures of the
appertaining row relative to the next holding structure or the
previous holding structure, the protrusions of adjacent rows face
each other. This is also capable of effectively counteracting
so-called edge lifting since, on both edge areas of the friction
lining into which the two ends of the rows extend next to a
depression, there is always arranged a protrusion of the adjacent
row.
[0013] An advantageous refinement is that, with holding structures
of adjacent rows that are arranged in opposite directions--as seen
in the manufacturing direction of the holding structures--the
beginning of each row is offset with respect to the end of the
appertaining adjacent row towards the middle of the brake lining
carrier plate. In this manner, as seen in the manufacturing
direction, there are no depressions, but rather only protrusions in
the edge area of the friction lining.
[0014] It is advantageous for the holding structures of adjacent
rows to be arranged so as to be offset with respect to each other,
whereby preferably a protrusion of one row comes to lie in the area
of the depressions of an appertaining adjacent row. This prevents
the depressions of adjacent rows from coming to lie directly next
to each other, thereby forming a continuous conduit for moisture,
dirty water, salt water, and the like.
[0015] According to yet another embodiment of the invention, the
rows are arranged in a fan formation in their lengthwise extension.
In this way, especially the contour of the friction lining found in
conventional disk brakes is taken into account. Here, the rows that
are arranged in a fan formation run essentially in the crosswise
direction or also approximately in the lengthwise direction of the
brake lining carrier plate.
[0016] In the case of rows that run essentially in the crosswise
direction of the brake lining carrier plate, it is advantageous for
the rows--relative to the installation position of the brake lining
carrier plate--to diverge outwards in the radial direction. This
results in favorable holding conditions for the friction lining,
especially in conventional disk brakes, since the holding
structures are consequently less stressed during braking, thus
diminishing the risk that the friction lining will shear off.
[0017] A further alternative embodiment of the invention provides
that the brake lining carrier plate has at least two areas, each
with rows of holding structures that run towards each other and
that are aligned in a fan formation, whereby the holding structures
of the one area are aligned counter to the holding structures of
the other area. In this manner, the machining of the holding
structures can be carried out in a way that is gentle on the brake
lining carrier plate, because the forces that act on one area
during the production of the holding structures and the forces that
act on the other area largely cancel each other out. This is
especially the case when the two areas are arranged
mirror-symmetrically relative to the middle crosswise axis and/or
relative to the middle longitudinal axis of the brake lining
carrier plate.
[0018] It is advantageous for the rows of the two areas to diverge
in opposite directions. In this manner, the manufacturing process
can easily provide especially large brake lining carrier plates
with the holding structures in that, in two consecutive work steps,
first the holding structures of the one area can be made and then,
after re-clamping the brake lining carrier plate into the device
that is producing the protrusions, the rows of the second area can
be produced.
[0019] The same approach may be taken with the alternative measure,
namely, that the rows of the two areas diverge towards the middle
of the brake lining carrier plate.
[0020] According to still another alternative measure, it can also
be provided that the rows of the two areas diverge in the same
direction. In this case, it is beneficial for the rows to have
essentially the same center of convergence. This is especially
advantageous if the rows of the two areas are produced
simultaneously in a single work cycle since the tool that is needed
to produce these rows can be manufactured easily. Here, it is
advantageous for the two areas to overlap in the edge area of their
sides facing each other in such a way that the ends of the rows of
the one area lie between the ends of adjacent rows of the other
area. In this manner, thanks to the large number of protrusions, a
firm holding effect of the friction lining on the brake lining
carrier plate is achieved precisely in the area that is
particularly highly stressed during braking.
[0021] The production of the tool for machining the brake lining
carrier plate is especially simple if the abutting holding
structures of adjacent rows each lie on a radius.
[0022] It is also advantageous for the holding structures to be
arranged at least in the edge area of the friction lining. After
all, in order to avoid edge lifting, it is sufficient if the
holding structures are present in the edge area of the friction
lining. In this context, the inner surface of the brake lining
carrier plate no longer has to be completely provided with holding
structures as well. However, an arrangement of holding structures
covering the entire surface additionally achieves a higher
absorption of the braking forces.
[0023] It is advantageous for the protrusions to have a height h of
about 1.40 mm to 1.80 mm, preferably about 1.60 mm, as measured
from the surface of the brake lining carrier plate. In this range,
an especially good bond of the friction lining to the brake lining
carrier plate is achieved and edge lifting can be counteracted.
[0024] The same approach is taken by the measure in which the
protrusions are aligned at an angle .alpha. of approximately
80.degree. to 84.degree. relative to the surface of the brake
lining carrier plate, preferably in the direction of each
associated depression.
[0025] It is advantageous for the brake lining carrier plate either
to be curved or to be essentially flat in shape. As a result, the
brake lining carrier plate can be used not only in a disk brake
system, but also in a drum brake system.
[0026] Additional objectives, advantages, features and application
possibilities of the present invention can be gleaned from the
description below of several embodiments, making reference to the
drawings. Here, all of the described and/or depicted features
constitute the subject matter of the present invention either on
their own or in any appropriate combination, also irrespective of
their compilation in the claims or the way in which they refer back

DETAILED DESCRIPTION
[0045] FIGS. 1 to 4 show a brake lining carrier plate 1 to hold a
friction lining of the type used, for example, in a vehicle brake
system. Such a brake system can be, for instance, a disk brake. As
a matter of principle, the brake lining carrier plate 1 can also be
employed in a drum brake or in another type of brake system.
[0046] The brake lining carrier plate 1 has holding structures 15
arranged in rows 6 on the lining side 2 for the friction lining
(not shown here). Each holding structure 15 has a protrusion 3 and
a depression 4, whereby the protrusion 3 is made in the carrier
plate surface 5 through the displacement of material, thereby
forming the depression 4. To form the brake structure, said
protrusion 3 engages with the friction lining (not shown here).
[0047] The rows 6 run essentially crosswise to the longitudinal
axis 7 of the brake lining carrier plate 1, and are arranged in a
fan formation, namely, in such a way that the rows 6--relative to
the installation position of the brake lining carrier
plate--diverge outwardly in the radial direction in the brake
system. In such fan formation, the angle of adjacent rows of the
holding structures is between about 0.degree. to about 15.degree..
Moreover, the abutting holding structures 15 of adjacent rows 6
each lie on a radius 11 (shown in FIG. 2).
[0048] In this embodiment (FIGS. 1 and 2), the holding structures
15 are arranged in the rows 6 in such a way that there is a
protrusion 10 at the beginning 8 and at the end 9 of each row 6.
The rows 6 also have two sections 12, 13 in which the positions of
the protrusion 3 and of the depression 4 of the holding structures
15 are opposing or alternating. Furthermore, the individual rows 6
with the holding structures 15 are arranged in such a way that they
are adjacent to the edge of the friction lining (not shown
here).
[0049] According to an embodiment (not shown here), it is, of
course, also possible for the holding structures 15 to be arranged
only in the edge area of the friction lining. As shown particularly
in FIGS. 1 and 2, the holding structures 15 cover substantially the
carrier plate surface, including portions of such surface adjacent
to oval opening 20.
[0050] In the embodiment according to FIGS. 1-5, the protrusions
are configured as crimps 3, whereby the free ends of the crimps are
bent back, for example, facing each associated depression 4. As can
be seen from FIG. 5, the crimps or protrusions 3 can have a height
h of about 1.4 mm to 1.8 mm, preferably approximately 1.6 mm, and
can be at an angle .alpha. towards each associated depression 4 of
approximately 80.degree. to 84.degree. relative to the surface 5 of
the brake lining carrier plate 1. Of course, the protrusions 3 can
also have other heights, and can be configured in another manner,
for example, in the form of pins, teeth, burrs, and the like.
[0051] FIG. 6 shows another embodiment of the brake lining carrier
plate 1a. It differs from the embodiment according to FIG. 1, among
other things, in that the position of each protrusion 3 and of each
depression 4 of the holding structures 15 alternates between
adjacent rows 6. As a result, the rows 6, which begin with a
depression 4 due to production-related reasons, are each adjacent
to a protrusion 3 in the edge area of the friction lining at the
end of the appertaining adjacent row--as seen in the manufacturing
direction of the holding structures 15. Consequently, depressions 4
and protrusions 3 alternate at the beginning and at the end of the
rows 6.
[0052] A refinement of the embodiment of the brake lining carrier
plate 1a according to FIG. 6 is shown in FIG. 7. The brake lining
carrier plate 1b shown in FIG. 7 differs, among other things, from
the embodiment according to FIG. 6 in that--as seen in the
manufacturing direction of the holding structures 15--the beginning
8 of each row 6 is offset relative to the end 9 of the appertaining
adjacent row 6 towards the middle portion 14 of the brake lining
carrier plate 1b.
[0053] According to another embodiment (not shown here), it is also
possible for the holding structures 15 of adjacent rows 6 to be
arranged offset with respect to each other, so that a protrusion 3
of the adjacent row 6 comes to lie in the area of the depression 4
of a row.
[0054] FIGS. 8 to 11, in turn, show another embodiment of the brake
lining carrier plate 1c. Elements of the brake lining carrier plate
1c that are the same as those of the previously explained
embodiments of the brake lining carrier plate 1, 1a, 1b are
designated with the same reference numerals. In this context,
reference is hereby made to the description relating to the
preceding embodiments. The embodiment according to FIGS. 8 to 11
differs from the preceding embodiments according to FIGS. 1, 6 and
7, among other things, in that the rows 6 run essentially in the
direction of the longitudinal axis 7 of the brake lining carrier
plate 1c in a fan formation. Here, the brake lining carrier plate
1c is divided into two areas 16, 17, each with rows 6 arranged in a
fan formation and having holding structures 15, whereby the two
areas 16 and 17 have an opposing arrangement of the protrusion 3
and of the depression 4 of the holding structures 15. In such fan
formation, the angle between adjacent rows of the holding
structures may be between about 0.degree. and about 15.degree..
Unlike in the embodiment of the brake lining carrier plate 1
according to FIG. 1, the rows 6 of the two areas 16, 17 diverge in
this embodiment towards the middle 14 of the brake lining carrier
plate 1c.
[0055] FIGS. 12 to 14 show a refinement id of the embodiment of the
brake lining carrier plate 1c according to FIGS. 8 to 11. The same
elements are once again designated with the same reference
numerals; in this context, reference is made to the explanations
pertaining to FIGS. 8 to 11. The embodiment 1d according to FIGS.
12 to 14 differs from the embodiment 1c according to FIGS. 8 to 11
in that the rows 6 of the two areas 16, 17 diverge in the same
direction, whereby they have essentially the same center of
convergence. Moreover, the two areas 16, 17 overlap in the edge
area 18 of their sides 19 facing each other in such a way that the
ends of the rows 6 of the one area 17 lie between the ends of
adjacent rows 6 of the other area 16. For example, the overlapping
in the edge area 19 can comprise two holding structures 15 of the
rows 6 of the areas 16, 17. It is also possible for fewer or more
holding structures 15 of the areas 16, 17 to overlap.
[0056] FIG. 15 shows yet another embodiment of the brake lining
carrier plate 1e. Elements of the brake lining carrier plate 1e
that are the same as those of the previously explained embodiments
of the brake lining carrier plate 1c, 1d are designated with the
same reference numerals. In this context, reference is hereby made
to the description relating to the preceding embodiments. In FIG.
15, the brake lining carrier plate 1e is divided into two areas 16,
17, each with rows 6 arranged in a fan formation with respect to
longitudinal axis 7. The rows 6 have holding structures 15, whereby
the two areas 16 and 17 have a complementary arrangement of the
protrusion 3 and of the depression 4 of the holding structures 15.
Unlike in the embodiments of the brake lining carrier plate 1c
according to FIGS. 8-11, the rows 6 of the area 17 diverge away
from the middle 18 of the brake lining carrier plate 1e, such that
the holding structures 15 are spaced more closely adjacent at the
middle 18 than at the peripheral edge of the brake lining carrier
plate 1e. In contrast, the rows 6 of the area 16 converge toward
the opposite peripheral edge of the brake lining carrier plate 1e,
such that the holding structures 15 are spaced more closely
adjacent at the peripheral edge than at the middle 18 of the brake
lining carrier plate 1e. The rows of areas 16 and 17 begin at the
middle 18 with depressions 4. One holding structure 15 at the
beginning of each row 6 of area 17 is adjacent to and overlaps with
one holding structure 15 at the beginning of each row of area 16 at
the middle 18 of the brake lining carrier plate 1e. Each row 6
begins with a depression 4 at the middle 18 and terminates with a
protrusion 10 at the peripheral edge of the brake lining carrier
plate 1e. However, the rows 6 of area 17 have a fan formation that
diverges away from the middle 18, and the rows 6 of area 16 have a
fan formation that converges toward the peripheral edge of the
brake lining carrier plate 1e. In such fan formation, the angle
between of adjacent rows of holding structures is between about
0.degree. and about 15.degree.. A holding structure 15 contour zone
22 is shown in phantom outline about the border of the brake lining
carrier plate 1e.
[0057] As a further alternative to the brake lining carrier plates
1, 1a and 1b shown in FIGS. 1-7, there is shown in FIG. 16 an
embodiment of the brake lining carrier plate if in which the rows 6
of holding structures 15 run essentially crosswise to the
longitudinal axis 7 of the brake lining carrier plate if and are
arranged in a fan formation. In contrast to the brake lining
carrier plates 1, 1a and 1b, in this embodiment 1f the rows 6 of
holding structures 15 are formed in one cutting direction without
alternating the positions of the protrusions 3 and depressions 4
between adjacent rows. Nor do the positions of the protrusions 3
and depressions 4 alternate above and below oval opening 20.
[0058] FIG. 17 shows another brake lining carrier plate 1g with
rows 6 of holding structures 15 formed in a manner similar to that
of the brake lining carrier plate 1f shown in FIG. 16. In FIG. 17,
the outer periphery of the brake lining carrier plate has a
configuration adapted for installation into a different vehicle.
Circular openings 24 are formed in areas 16 and 17 in the brake
lining carrier plate.
[0059] FIG. 18 illustrates yet another alternative brake lining
carrier plate 1h according to the invention with rows 6 of holding
structures 15 formed in a manner similar to that of brake lining
carrier plate if shown in FIG. 16. In FIG. 18, the outer periphery
of the brake lining carrier plate has a configuration adapted for
installation into still a different vehicle.
[0060] It is to be understood that while the invention has been
described in conjunction with the detailed description thereof, the
foregoing description is intended to illustrate and not limit the
scope of the invention, which is defined by the scope of the
appended claims. Other aspects, advantages, and modifications are
within the scope of the following claims.
